Gauthier, Marcos, thanks, this solved the problem! I did notice some strange behavior: I first had to add an Image instance with the Add New menu. Only then could I upload an image inside the TinyMCE editor. This will maybe confuse my users, but at least I will have the solution ready if it happens again.
Thanks again, Maarten _______________________________________________ Product-Developers mailing list [email protected] https://lists.plone.org/mailman/listinfo/plone-product-developers
